The AEC's (the CIE ones at least) had a similar Spanner type of boiler. It was located in the guard's compartment (no enclosure that I saw other than a simple wire mesh screen) on the left side, against the outer wall, when looking toward the gangway or on right when looking toward the cab end. Its exhaust flue was very similar to that on the GN coaches as just discussed but obviously at an angle from vertical and closer to the side. There was a 'Danfoss' temperature probe installed in the flue to confirm firing.
The previous lower capacity Vapor Clarkson boilers had a smaller diameter flue with a cap but no surrounding 'box'. As far as I know the GN, later UTA AEC's had the original boilers right to the end.
The old type VC boilers, flash tube type with downward firing from the top, a standard 'Vapor' design, were significantly noisier in operation.
Colm's Diesel Dawn book makes refers to the railcar boilers.

It's a partial shot of a L12 brake third in the NIR blue & cream livery, in a BUT set.
The windows visible in the guards van section were clear although there would appear to be horizontal bars behind the windows, presumably to protect the glass, from luggage,parcels etc.
Norman identifies the coach as being either 591 or 592. The photo was taken in 1968.
Hope this helps.

There is a picture in Norman Johnston's The GNR in Colour, on P73 which shows BUT Trailer 114, an L13 Brake 3rd. All windows seem to be clear except for the boiler compartment which looks opaque.
There is also a picture on P67 in which the boiler compartment window looks different to the others.

Thanks for the replies. Glover, had a look at that picture but it's taken on the corridor side of the coach but I'll go with the Guard & Luggage compartments having clear glass and maybe add the 'bar'. I was resigning myself to having to add red boilers as per Jeremy's post than along comes David with some evidence to suggest the boiler compartments had opaque glass. If it's a toss up between adding red boilers or opaque glass then the glass wins.

GNR(I) BUT converted coaches finished. It's always a relief to get to the end of a project.
L12 Brake/3rd No. 94
D5 Brake/1st No. 231
B9 Buffett Car/3rd No. 124
After all the work on the bar interior there's not much to see from the outside unless I put in lights but for me that's a bridge to far.
